在前面测试通过odoo登录的功能，这次的问题重点是如何访问后台具体的业务类的接口呢？这次就以我们在odoo中安装的lunch模块为例，目标是获取lunch.alert的数据，如下图
具体过程接上次文章，继续完善OdooJsonRpc类的代码，首先是基础代码，这个是需要提供具体的model名称和具体方法，也是是一个很基础的方法，后台的odoo网站会利用类似C#反射的机制调用目标类的方法。
/** * Calls the method of that particular model * @param model Model name * @param method Method name of particular model * @param args Array of fields * @param kwargs Object */ public call(model: string, method: string, args: any, kwargs?: any) { kwargs = kwargs || {}; let params = { model: model, method: method, args: args, kwargs: kwargs == false ? {} : kwargs, context: this.getContext() }; return this.sendRequest("/web/dataset/call_kw", params); }
调用以上基础call方法的几个基本封装函数有如下几个，基本实现了对数据的CRUD功能，当然基本上是针对一条数据的操作
/** * Reads that perticular fields of that particular ID * @param model Model Name * @param id Id of that record which you want to read * @param mArgs Array of fields which you want to read of the particular id */ public read(model: string, id: number, mArgs: any): Promise<any> { let args = [ id, [mArgs] ] return this.call(model, 'read', args) } /** * Provide the name that you want to search * @param model Model name * @param name Name that you want to search */ public nameSearch(model: string, name: string): Promise<any> { let kwargs = { name: name, args: [], operator: "ilike", limit: 0 } return this.call(model, 'name_search', [], kwargs) } /** * Provide the IDs and you will get the names of that paticular IDs * @param model Model name * @param mArgs Array of IDs that you want to pass */ public nameGet(model: string, mArgs: any): Promise<any> { let args = [mArgs] return this.call(model, 'name_get', args) } /** * Create a new record * @param model Model name * @param mArgs Object of fields and value */ public createRecord(model: string, mArgs: any) { let args = [mArgs]; return this.call(model, "create", args, null) } /** * Delete the record of particular ID * @param model Model Name * @param id Id of record that you want to delete */ public deleteRecord(model: string, id: number) { let mArgs = [id] return this.call(model, "unlink", mArgs, null) } /** * Updates the record of particular ID * @param model Model Name * @param id Id of record that you want to update the. * @param mArgs The Object of fields and value that you want to update * (e.g) * let args = { * "name": "Mtfa" * } */ public updateRecord(model: string, id: number, mArgs: any) { let args = [ [id], mArgs ] return this.call(model, "write", args, null) }
针对单条数据的读取，这里还有另外一种方法，类似上面的read函数
/** * Loads all data of the paricular ID * @param model Model name * @param id Id of that particular data which you want to load */ public load(model: string, id: number): Promise<any> { let params = { model: model, id: id, fields: [], context: this.getContext() } return this.sendRequest("/web/dataset/load", params) }
还有对odoo多条件查询的情况，尤其还有分页的问题，这里也有这样一个很实用的分页查询的方法，这个在日后app的开发中会经常用到
/** * Fires query in particular model with fields and conditions * @param model Model name * @param domain Conditions that you want to fire on your query * (e.g) let domain = [ * ["id","=",11] * ] * @param fields Fields names which you want to bring from server * (e.g) let fields = [ * ["id","name","email"] * ] * @param limit limit of the record * @param offset * @param sort sorting order of data (e.g) let sort = "ascending" */ public searchRead(model: string, domain: any, fields: any, limit: number, offset: any, sort: string) { let params = { model: model, fields: fields, domain: domain, offset: offset, limit: limit, sort: sort, context: this.getContext() }; return this.sendRequest("/web/dataset/search_read", params); }
到此，访问odoo具体业务类的OdooJsonRpc类封装完毕，完整的代码在这里。接下来怎么获取我们的lunch.alert数据呢？？
首先定义我们访问odoo业务类的成员变量，这里我们的model类是lunch.alert,需要获取的字段是message和id,其他参数我们暂使用默认的值
private lunchAlert = "lunch.alert"; private fields = ["message", "id"]; private domain = [] private sort = "" private limit = 0 private offset = 0 private items: Array<{ id: number, message: string }> = []
第二步是，与odoo后台网站交互获取数据的过程
private TestMyOdooModel() { this.odooRpc.searchRead(this.lunchAlert,this.domain, this.fields, this.limit, this.offset,this.sort) .then((lunchAlerts: any) => { let json = JSON.parse(lunchAlerts._body); if (!json.error) { let query = json["result"].records for (let i in query) { this.items.push ({ id: query[i].id, message: query[i].message }) } this.utils.presentAlert("Lunch Message", this.items[0].message,[{text: "Ok"}]) } else { this.utils.presentAlert("LunchAlert", "Parse lunch alert error",[{text: "Ok"}]) } }) }
如果正确获取数据，我们会弹出第一条数据对应的message.
编译打包成*.apk，在手机上测试，确实成功了，如下图所示。
由于这些都是测试阶段的代码，将来可能会改变，现阶段把这些代码全部放在这里。
